AI Technical Summary

Benefits of technology

The design effectively prevents damage to the locking portions of the connector cover by distributing tensile forces across the elastic hold arms and storing them within the arm storing portions, ensuring the connector cover remains functional under tensile stress.

Problems solved by technology

In a connector cover disclosed in Patent Document 1, there is a fear that, when transporting the connector cover, or when arranging a wire harness to a vehicle, as shown in FIG. 18, if a tensile force is applied to a corrugated tube C with a portion (a portion surrounded by a circle in FIG. 18) of a connector cover A caught by something, a load is applied to locking parts B of the vertically divided cover and they are damaged easily.
Therefore, when a tensile force is applied to the corrugated tube, similarly to the connector cover of the patent document 1, a load is easily applied to locking portions of the vertically divided cover and they are damaged easily.

embodiment 1

[Embodiment 1]

[0036]FIG. 1 is a view showing a state of a connector cover 1 according to an embodiment 1 before an upper cover 30 and a lower cover 10 thereof are assembled together so as to sandwich an end of a connector housing 100 and an end of a corrugated tube C. FIG. 2 shows a state of the connector cover 1 according to the embodiment 1 in which the upper cover 30 and lower cover 10 are assembled together so as to sandwich the end of the connector housing 100 and the end of the corrugated tube C. FIG. 3 is a section view of the upper side cover 30 and lower cover 10 in a state where they face each other in their mutually locking direction. FIG. 4 is a section view of the connector cover 1 in a state where upper cover 30 and lower cover 10 are locked to each other. FIGS. 5A to 5D are multiple views of the lower cover 10 when viewed from different directions: Specifically, FIG. 5A is a perspective view; FIG. 5B is a top view; FIG. 5C is a view when viewed from the side thereof t...

embodiment 2

[Embodiment 2]

[0096]Next, description is given of a connector cover 2 according to an embodiment with reference to FIGS. 10, 11A and 11B.

[0097]FIG. 10 is a view showing a state before an upper cover 30 and a lower cover 10 of the connector cover 2 according to the embodiment 2 are assembled together so as to sandwich an end of a connector housing 100 and an end of a corrugated tube C. FIG. 11A is a perspective view of the upper cover 30, and FIG. 11B is a perspective view of the lower cover 10.

[0098]The connector cover 2 according to the embodiment 2 is different from the connector cover 1 of the embodiment 1 in that it includes ribs 50 which respectively extend continuously from the outer surfaces of the two side walls 14a, 14a of the tube placement wall 14 of the lower cover 10 to the outer surfaces of the pair of elastic hold arms 20, 20.

[0099]The remaining configurations are similar to the embodiment 1. The same composing parts as the embodiment 1 are given the same designations...

Abstract

A lower cover of the connector cover includes a pair of elastic hold arms projected upward from both side walls of a tube placement wall. An upper cover includes a pair of arm storing portions for storing the pair of elastic hold arms. The pair of arm storing portions respectively have facing surfaces. The facing surfaces respectively face side surfaces of the pair of hold arms perpendicular to the wire lead-out direction, when the lower cover and the upper cover are connected to each other.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application is based on and claims priority from Japanese Patent Applications No. 2017-174163 filed on Sep. 11, 2017, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Field of the Invention[0003]The invention relates to a connector cover which is divided vertically and is assembled so as to sandwich a wire lead-out side end of a connector housing and an end of a corrugated tube.[0004]2. Description of Related Art[0005]Conventionally, for example, a connector cover for use with a connector of a wire harness arranged in a vehicle and the like is divided vertically and is assembled so as to sandwich a wire lead-out side end of a connector housing and an end of a corrugated tube.[0006]For example, Patent Documents 1 and 2 disclose a connector cover whose upper and lower covers are connected to each other.[0007]In a connector cover disclosed in Patent Document 1, there is a fear that, when transporting...
